Description
The AT28C256 is a high-performance electrically erasable and programmable read
only memory. Its 256K of memory is organized as 32,768 words by 8 bits. Manufac-
tured with Atmel
’
s advanced nonvolatile CMOS technology, the device offers access
times to 150 ns with power dissipation of just 440 mW. When the device is deselected,
the CMOS standby current is less than 200
μA.
